TLDR

Requirements engineering prioritization ranks requirements by importance to guide release decisions and enhance system economic value. This study aims to identify and analyze existing prioritization techniques in light of specific research questions. The authors conducted a keyword‑based search of journal articles, conference papers, workshops, symposiums, book chapters, and IEEE bulletins to locate primary studies on requirements prioritization. Seventy‑three primary studies were selected, including 13 journal articles, 35 conference papers, 8 workshop papers, 2 symposium contributions, 2 IEEE bulletins, and the remaining book chapters.

Abstract

Context: During requirements engineering, prioritization is performed to grade or rank requirements in their order of importance and subsequent implementation releases. It is a major step taken in making crucial decisions so as to increase the economic value of a system. Objective: The purpose of this study is to identify and analyze existing prioritization techniques in the context of the formulated research questions. Method: Search terms with relevant keywords were used to identify primary studies that relate requirements prioritization classified under journal articles, conference papers, workshops, symposiums, book chapters and IEEE bulletins. Results: 73 Primary studies were selected from the search processes. Out of these studies; 13 were journal articles, 35 were conference papers and 8 were workshop papers. Furthermore, contributions from symposiums as well as IEEE bulletins were 2 each while the total number of book chapters amounted
